For current feedback the output current must be sampled and not the output voltage. If the output circuit is broken and a current sensing element (for example a resistor) is inserted at which the feedback network is connected then the feedback has current sampling. If the output voltage is sampled directly, without any current sensing device or any part of the feedback network inserted in series with the output, the feedback is voltage sensing.
